Key takeaway
If there is a seizure, a fever, severe confusion, hallucinations, or an irregular heartbeat, call 911. Do not put a seizing person in a car. Alcohol withdrawal can become life-threatening quickly, and most people who get care still recover. Neither fact means you wait out a seizure for a rehab callback.

If there is a seizure, a fever, severe confusion, hallucinations, or an irregular heartbeat, call 911. Do not put a seizing person in a car. Let the crew come to you. Do not wait on a rehab callback while this is happening.

These signs do not wait
Alcohol withdrawal may quickly become life-threatening. Contact a provider or go to an emergency department if you think you are in withdrawal, especially if you were drinking often and recently stopped. The signs that make it an emergency are seizures, fever, severe confusion, hallucinations, and irregular heartbeats. If you are already in a hospital for another reason, tell the staff you have been drinking heavily so they can watch for withdrawal.
Death is possible, especially if delirium tremens occurs. Most people who go through alcohol withdrawal make a full recovery. Both sentences are true. Neither one is a reason to wait out a seizure at home to see which group you are in.
If your hands tremble when you go without alcohol, do not try to quit on your own. That course may be life-threatening. Work with a provider. Severe vomiting, hallucinations, confusion, fever, or convulsions belong in emergency care. A taper is a clinician's order, not a schedule you build from a page.
Delirium tremens has its own clock
Delirium tremens is a severe form of alcohol withdrawal and a medical emergency. Symptoms most often start 48 to 96 hours after the last drink. They can worsen quickly: agitation, body tremors, sudden severe confusion, fever, hallucinations, and seizures. Seizures may show up without the rest of that picture. A quiet stretch after the last drink is not an all-clear. The longer clock for ordinary symptoms is in the alcohol detox timeline. The wider list of early signs is in alcohol withdrawal symptoms.
Moderate to severe symptoms may need a hospital, with watching for hallucinations and delirium tremens, checks of blood pressure, body temperature, heart rate, and blood chemicals, and fluids or medicines through a vein. Sedatives continue until withdrawal is complete. Mild to moderate symptoms are often treated outside the hospital, with someone staying, daily visits until the person is stable, and sedatives a clinician provides. That split is an exam. Clinicians often use CIWA-Ar for it. A partner should not run that scale at the kitchen table.
A sudden stop after chronic heavy drinking can be life-threatening. Severe withdrawal, delirium tremens, or seizures are not a fit for detox outside a medical setting. Detoxification alone is not sufficient care. Ask the hospital what follow-up is arranged before discharge. How to ask for an assessment date, after you are safe enough to be on the phone, is in getting into treatment this week.
MedlinePlus lists Alcoholics Anonymous, Al-Anon, and SMART Recovery among support resources. SMART Recovery is a separate mutual-help program. A meeting does not monitor a heart rhythm. Once a clinician has said the emergency has passed, meetings you can search are at the meeting finder.
Call or text (800) 653-9376 when the emergency has passed and you need help asking what level of withdrawal care should come next.

Common Questions
Which alcohol withdrawal signs are an emergency?
MedlinePlus says to call 911 or go to an emergency department for seizures, fever, severe confusion, hallucinations, or irregular heartbeats. Contact a provider or go to an emergency department if you think you are in withdrawal, especially after frequent drinking that just stopped. Tell hospital staff if you have been drinking heavily. Severe vomiting, hallucinations, confusion, fever, or convulsions are on the same emergency list. Do not put a seizing person in a car.
Can I wait to see if the shaking passes?
If your hands tremble when you are without alcohol, MedlinePlus says not to try to quit on your own. That course may be life-threatening. Work with a provider. Death is possible, especially if delirium tremens occurs. Most people who go through withdrawal make a full recovery. Both sentences are true. Neither one means you wait out a seizure at home.
When do delirium tremens and seizures usually start?
Delirium tremens symptoms most often occur 48 to 96 hours after the last drink. They may occur 7 to 10 days later, and they can worsen quickly. The list includes agitation, body tremors, sudden severe confusion, fever, hallucinations, and seizures. Seizures may occur without the other delirium tremens symptoms, most often in the first 12 to 48 hours, most often in people who have had complicated withdrawal before, and they are usually whole-body seizures. A quiet stretch after the last drink is not an all-clear.
What happens in the emergency department?
Moderate to severe symptoms may need a hospital, with watching for hallucinations and delirium tremens, monitoring of blood pressure, temperature, heart rate, and blood chemicals, fluids or medicines through a vein, and sedatives until withdrawal is complete. Mild to moderate symptoms are often treated as an outpatient, with someone staying, daily visits, and sedatives a clinician provides. That split is an exam. A benzodiazepine dose is the hospital's order.
Is detox itself the whole treatment?
No. TIP 45 says detoxification alone is not sufficient care, and that severe withdrawal, delirium tremens, or seizures are not a fit for detox outside a medical setting. A sudden stop after chronic heavy drinking can be life-threatening. Ask the hospital what follow-up is arranged before discharge. A meeting does not monitor a heart rhythm. MedlinePlus lists Alcoholics Anonymous, Al-Anon, and SMART Recovery among support resources. SMART Recovery is a separate mutual-help program.
